All multicellular organisms begin as zygotes. Shortly after forming, a zygote begins to divide. The single-celled zygote divides to form two new cells, then four, then elght, and so on. The division of each of these cells to form two new cells is called cleavage. Before each cleavage, or cell division, the genetic material in each cellis duplicated. This enables a cell to pass on a complete set of genes to the new cells formed by cell division. As you have read, the embryo develops In Its mother's uterus. It grows and becomes more complex until it is developed enough to leave the mother's body. The period from fertilization to birth, during which the offspring develops Inside the mother's body, is called pregnancy or the gestation perlod. In humans, the gestation period lasts about nine months. Pregnancy in humans is often discussed in terms of three three-month perlods called trimesters. Each trimester is characterized by specific changes in the developing offspring.

Are they describing "mitosis" or "melosis" In this paragraph? How can you tell?

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

layer 3 is younger than layer 6.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

because it travels in smaller waves then all other colors, causing it to be the most visible color
